Description

STANZVERFAHREN UND DADURCH GEFERTIGTE BAUTEILE  PUNCHING PROCESSES AND COMPONENTS THEREFORE MADE
Die Erfindung betrifft ein Verfahren zum Herstellen von Fahrzeugsitzkompo- nenten, insbesondere von Bauteilen eines Sitzverstellers durch schneidtechnische Bearbeitung eines Halbzeugs. Die Erfindung betrifft ferner eine Fahrzeugsitzkomponente, insbesondere ein Bauteil für einen Sitzversteller eines Kraftfahrzeugsitzes, mit einem durch schneidtechnische Bearbeitung erstellten Randbereich und einem durch den Randbereich begrenzten Basisabschnitt. The invention relates to a method for producing Fahrzeugsitzkompo- components, in particular of components of a seat adjuster by cutting processing of a semifinished product. The invention further relates to a vehicle seat component, in particular a component for a seat adjuster of a motor vehicle seat, with an edge region created by cutting-machining and a base section bounded by the edge region.
Aus dem Stand der Technik ist es bekannt, Fahrzeugsitzkomponenten, insbesondere die Bauteile eines Sitzverstellers, mittels dem ein Fahrzeugsitz an die persönlichen Bedürfnisse des jeweiligen Nutzers angepasst werden kann, aus einem hochfesten Halbzeug durch Feinschneiden herauszubilden und diese in einem nachfolgenden, gesonderten Verfahrensschritt durch Einsatzhärten vollständig in einem Ofen zu härten. Der Fahrzeugsitzkomponente, insbesondere ihren Funktionsabschnitten, bspw. einer Verzahnung, wird dadurch die für die Funktion erforderliche Materialeigenschaft verliehen. Insbesondere kann so bspw. eine ausreichende Härte der Verzahnung sowie eine Festigkeitserhöhung im Bereich des Zahngrunds erreicht werden. From the prior art, it is known vehicle seat components, in particular the components of a seat adjuster, by means of which a vehicle seat can be adapted to the personal needs of the respective user, from a high-strength semi-finished by fine cutting and this completely in a subsequent, separate process step by case hardening to harden in an oven. The vehicle seat component, in particular its functional sections, for example a toothing, is thereby given the material property required for the function. In particular, for example, a sufficient hardness of the toothing and an increase in strength in the region of the tooth base can be achieved.
Obgleich es für eine zuverlässige Funktion der Fahrzeugsitzkomponenten in der Regel lediglich erforderlich ist, die durch die schneidtechnische Bearbeitung ausgebildeten Randbereiche der Fahrzeugsitzkomponente einer Wärmebehand- lung zu unterziehen, erfolgt bei den aus dem Stand der Technik bekannten Verfahren durchgängig eine vollständige Wärmebehandlung der schneidtechnisch hergestellten Fahrzeugsitzkomponenten. Hieraus resultieren nicht nur hohe Bearbeitungskosten. Es werden überdies die mechanischen Eigenschaften der Fahrzeugsitzkomponenten negativ beeinflusst, nachdem in den von den Rand- bereichen entfernten Abschnitten der Fahrzeugsitzkomponente eine hohe Duk- tilität gewünscht ist, damit die Fahrzeugsitzkomponente im Crashfall dazu geeignet ist, durch Verformung Crashenergie abzubauen. Ein weiterer Nachteil der bekannten, üblicherweise durch Fineblanking, d. h. Feinschneiden der Komponenten aus einem Halbzeug hergestellten Fahrzeugsitzkomponenten besteht darin, dass deren Glattschnittanteil nicht ausreichend ist, so dass auf eine Oberflächenbearbeitung nicht verzichtet werden kann, um die gewünschten Oberflächeneigenschaften zu erreichen. Although it is generally only necessary for a reliable function of the vehicle seat components to heat treat the edge regions of the vehicle seat component formed by the cutting machining, in the methods known from the prior art a complete heat treatment of the vehicle seat components produced by cutting takes place. This not only results in high processing costs. Moreover, the mechanical properties of the vehicle seat components are adversely affected, having In the case of a crash, the vehicle seat component is designed to reduce crash energy by deformation. A further disadvantage of the known vehicle seat components usually produced by fine blanking, ie fine cutting of the components from a semifinished product, is that their straight cut portion is not sufficient, so that a surface treatment can not be dispensed with in order to achieve the desired surface properties.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Herstellen von Fahrzeugsitzkomponenten, insbesondere von Bauteilen eines Sitzverstellers durch schneidtechnische Bearbeitung eines Halbzeugs bereitzustellen, das sich einfach und kostengünstig durchführen lässt und die Herstellung nachbearbei- tungsarmer Bauteile ermöglicht. Ferner liegt der Erfindung die Aufgabe zugrunde, eine Fahrzeugsitzkomponente bereitzustellen, die sowohl dazu geeignet ist, um Crashenergien durch Deformation abzubauen als auch eine ausreichende Verschleißfestigkeit aufweist. Die Erfindung löst die Aufgabe durch ein Verfahren mit den Merkmalen des Anspruchs 1 sowie eine Fahrzeugsitzkomponente mit den Merkmalen des Anspruchs 8. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben. Wesentlich für das erfmdungsgemäße Verfahren zum Herstellen von Fahrzeugsitzkomponenten, insbesondere von Bauteilen eines Sitzverstellers durch schneidtechnische Bearbeitung eines Halbzeuges sind die Verfahrensschritte lokales Erwärmen des Halbzeugs im Bereich einer vorgesehenen Schnittführung der auszuschneidenden Fahrzeugsitzkomponenten und Ausschneiden der Fahrzeugsitzkomponenten aus dem Halbzeug entlang der Schnittführung während oder kurzzeitig nach dem Erwärmen. The invention has for its object to provide a method for producing vehicle seat components, in particular of components of a seat adjuster by cutting processing of a semi-finished, which can be carried out easily and inexpensively and allows the production nachbearbei- tion poor components. It is a further object of the present invention to provide a vehicle seat component which is suitable for both reducing crash forces by deformation and having sufficient wear resistance. The invention achieves the object by a method having the features of claim 1 and a vehicle seat component having the features of claim 8. Advantageous developments of the invention are specified in the dependent claims. Essential for the erfmdungsgemäße method for producing vehicle seat components, in particular of components of a seat adjuster by cutting processing of a semifinished product are the process steps local heating of the semifinished product in the area of an intended cut the auszuschneidenden vehicle seat components and cutting the Vehicle seat components from the stock along the cut during or shortly after heating.
Gemäß der Erfindung ist vorgesehen, dass das Halbzeug, aus dem die Fahr- zeugsitzkomponente im Rahmen einer schneidtechnischen Bearbeitung bspw. durch Feinschneiden herausgearbeitet wird, vor dem Zuschnitt erwärmt wird, wobei die Erwärmung auf Bereiche der Schnittführung beim Zuschnitt der Fahrzeugsitzkomponente aus dem Halbzeug beschränkt ist. Die Erwärmung kann dabei auf alle Bereiche ausgedehnt werden, welche der schneidtechni- sehen Bearbeitung unterliegen. Es können jedoch auch selektiv nur Teilbereiche der Schnittführung erwärmt werden, so dass sich aus der Erwärmung resultierende Materialeigenschaften der sich aus der Schnittführung ergebenden Schnittkanten der Fahrzeugsitzkomponenten bereichsweise eingestellt werden können. According to the invention, it is provided that the semifinished product, from which the vehicle seat component is machined, for example, by fine blanking, is heated prior to cutting, the heating being restricted to areas of the cut when the vehicle seat component is cut from the semifinished product , The heating can be extended to all areas which are subject to the cutting technology. However, it is also possible selectively to heat only partial areas of the cut, so that the material properties resulting from the heating of the cut edges of the vehicle seat components resulting from the cut can be adjusted in regions.
Die schneidtechnische Bearbeitung des Halbzeugs zur Herstellung der Fahrzeugsitzkomponenten erfolgt gemäß der Erfindung während oder kurzzeitig nach dem Erwärmungsprozess des Halbzeugs auf die gewünschte Prozesstemperatur. Neben der Verbesserung der Materialeigenschaften, insbesondere der Härte und/ oder Festigkeitswerte der späteren Schnittkanten der Fahrzeugsitzkomponenten werden durch die Erwärmung die zur schneidtechnischen Bearbeitung erforderlichen Bearbeitungskräfte, bspw. Stanzkräfte in erheblichem Umfang reduziert. Darüber hinaus wird die Qualität des Schnitts gegenüber den aus dem Stand der Technik bekannten, kalt geschnittenen Halbzeugen gestei- gert, was zu einem erhöhten Glattschnittanteil führt, der bis zu 100 % betragen kann. The cutting-technical processing of the semifinished product for producing the vehicle seat components takes place according to the invention during or shortly after the heating process of the semifinished product to the desired process temperature. In addition to the improvement of the material properties, in particular the hardness and / or strength values of the later cutting edges of the vehicle seat components, the machining forces required for cutting machining, for example punching forces, are reduced to a considerable extent by the heating. In addition, the quality of the cut is increased compared with the cold-cut semi-finished products known from the prior art, which leads to an increased proportion of smooth cuts, which can be up to 100%.
Die erfmdungsgemäße Erwärmung des Halbzeugs führt somit insgesamt zu einer Verbesserung der Produkteigenschaften der Fahrzeugsitzkomponenten, nämlich dazu, dass die ausgewählten Randbereiche die geforderte Festigkeit aufweisen und darüber hinaus der übrige, durch den Randbereich begrenzte Basisabschnitt eine ausreichende Duktilität besitzt, um im Crashfall Crashenergien durch Verformung abzubauen. Darüber hinaus erleichtert die Erwärmung den Herstellungsprozess der Fahrzeugsitzkomponenten, wobei zur Durchführung des Verfahrens weniger Energie aufgewendet werden muss. Auch kann durch eine geeignete Erwärmung des Halbzeugs auf spätere Wärmebehandlungen und/oder Oberflächenbehandlungen der Fahrzeugsitzkomponenten verzichtet werden, was zu einer ergänzenden Reduzierung der Herstellungskosten beiträgt. The erfmdungsgemäße heating of the semi-finished product thus leads to an overall improvement in the product properties of the vehicle seat components, namely the fact that the selected edge regions have the required strength and, moreover, the rest of the base region delimited by the edge region has sufficient ductility in order to reduce crash energies by deformation in the event of a crash. In addition, the heating facilitates the manufacturing process of the vehicle seat components, which requires less energy to perform the method. Also can be dispensed with by a suitable heating of the semifinished product on subsequent heat treatments and / or surface treatments of the vehicle seat components, which contributes to a complementary reduction in manufacturing costs.
Zur weiteren Verbesserung der Materialeigenschaften der Fahrzeugsitzkomponenten ist nach einer weiteren Ausgestaltung der Erfindung vorgesehen, dass die Fahrzeugsitzkomponenten im Anschluss an ihren Zuschnitt partiell, insbe- sondere im Bereich ihrer Schnittkanten oder vollständig erwärmt werden. In order to further improve the material properties of the vehicle seat components, it is provided according to a further embodiment of the invention that the vehicle seat components are partially heated after their blank, in particular in the region of their cutting edges or completely.
Durch diese Ausgestaltung der Erfindung, die grundsätzlich eine frei wählbare Erwärmung der ausgeschnittenen Fahrzeugsitzkomponente vorsieht, können einzelne Bereiche in ihrer Materialeigenschaft in der geforderten Weise eingestellt werden. Auch kann die gesamte Fahrzeugsitzkomponente entlang ihrer Schnittkante durch die kontrollierte Erwärmung in ihrer Eigenschaft an die Anforderungen angepasst werden, wobei unterschiedliche Bereiche der Schnittkanten durch unterschiedliche Erwärmungen unterschiedliche Materialeigenschaften aufweisen können. Insgesamt erlaubt somit die nachfolgende Erwärmung der Schnittkanten in besonders vorteilhafter Weise die Anpassung der Fahrzeugsitzkomponente.  By this embodiment of the invention, which basically provides a freely selectable heating of the cut-out vehicle seat component, individual areas can be adjusted in their material properties in the required manner. Also, the entire vehicle seat component along its cutting edge by the controlled heating in their capacity to be adapted to the requirements, wherein different areas of the cutting edges may have different material properties due to different heating. Overall, therefore, the subsequent heating of the cut edges in a particularly advantageous manner allows the adjustment of the vehicle seat component.
Die lokale Erwärmung des Halbzeugs vor der schneidtechnischen Bearbeitung, aber auch die vorteilhafterweise vorgesehene partielle oder vollständige Erwärmung der ausgeschnittenen Fahrzeugsitzkomponente kann grundsätzlich in beliebiger Weise erfolgen. So besteht bspw. die Möglichkeit, die Fahrzeugsitzkomponenten bereits in einer einer Schneidvorrichtung vorgelagerten Vorrichtung zu erwärmen, bspw. durch geeignete Öfen oder aber durch wärmeerzeugendes Stauchen. Denkbar ist auch die Verwendung eines in die Schneidvor- richtung integrierten Auf heizsystems oder eines nachgeschalteten Auf heizsystems, in dem die vorteilhafterweise vorgesehene, sich an den Zuschnitt anschließende Wärmebehandlung vorgenommen werden kann. The local heating of the semifinished product prior to the cutting-technical processing, but also the advantageously provided partial or complete heating of the cut-out vehicle seat component can basically in done in any way. For example, there is the possibility to heat the vehicle seat components already in a device upstream of a cutting device, for example by suitable ovens or by heat-generating upsetting. It is also conceivable to use a heating system integrated in the cutting device or a downstream heating system in which the advantageously provided heat treatment following the blank can be carried out.
Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vor- gesehen, dass das lokale Erwärmen des Halbzeugs und/oder die partielle oder vollständige Erwärmung der zugeschnittenen Fahrzeugsitzkomponente durch Einwirkung einer Wärmestrahlung, insbesondere durch eine gerichtete Strahlung erreicht wird. Durch die entsprechende Erwärmung des Halbzeugs und/oder der zugeschnittenen Fahrzeugsitzkomponente lässt sich der zu er- wärmende Bereich sehr genau begrenzen, so dass im Wesentlichen nur diejenigen Bereiche einer Wärmebehandlung unterliegen, in denen später eine entsprechende Härte und/oder Festigkeitserhöhung erwünscht ist. According to a particularly advantageous embodiment of the invention, however, it is provided that the local heating of the semifinished product and / or the partial or complete heating of the cut vehicle seat component is achieved by the action of a heat radiation, in particular by a directed radiation. Due to the corresponding heating of the semifinished product and / or the cut vehicle seat component, the area to be heated can be limited very precisely so that essentially only those areas undergo a heat treatment in which a corresponding hardness and / or increase in strength is desired later.
Insbesondere durch die Verwendung einer gerichteten Strahlung lässt sich in besonderer Weise ein sehr begrenzter Wärmeeintrag erreichen, so dass die Bereiche, deren Materialeigenschaften unverändert bleiben sollen, keine Erwärmung erfahren. Die Verwendung einer hochenergetischen Strahlung ermöglicht es, den Bereich der zu härtenden Schnittkanten punktförmig oder flächig in sehr kurzer Zeit auf die zur Härtung notwendige Temperatur zu erhitzen, wobei der für die Härtung erforderliche Abkühlvorgang aufgrund der sehr schnellen Erwärmung durch die Strahlung direkt im Anschluss über die Fahrzeugsitzkomponente selbst erfolgen kann, die wegen der Trägheit der Wärmeleitung in der kurzen Zeit nicht mit erhitzt wird. Nach einer besonders vorteilhaften Weiterbildung der Erfindung ist dabei vorgesehen, dass die partielle oder vollständige Erwärmung der zugeschnittenen Fahrzeugsitzkomponente durch eine über eine Strahlweiche, einen Spiegel und/oder eine Strahlbeugung erfolgende Umlenkung der gerichteten Strahlung erfolgt. Die Verwendung einer Strahlweiche , eines Spiegel und/oder einerIn particular, by the use of a directed radiation can be achieved in a special way, a very limited heat input, so that the areas whose material properties are to remain unchanged, do not experience warming. The use of a high-energy radiation makes it possible to heat the area of the edges to be hardened punctiform or flat in a very short time to the necessary temperature for curing, wherein the cooling required for curing due to the very rapid heating by the radiation directly after the Vehicle seat component itself can be done, which is not heated because of the inertia of the heat conduction in the short time. According to a particularly advantageous development of the invention, it is provided that the partial or complete heating of the cut vehicle seat component takes place by means of a deflecting of the directed radiation which takes place via a beam switch, a mirror and / or a beam diffraction. The use of a beam splitter, a mirror and / or a
Strahlbeugung ermöglicht es, einen möglicherweise bereits zur Erwärmung des Halbzeugs verwendete Strahlungsquelle in unveränderter Form auch zur partiellen oder vollständigen Erwärmung der zugeschnittenen Fahrzeugsitzkomponente zu verwenden, wobei die Steuerung und Ausrichtung der Strahlungs- quelle dabei über die Strahlweiche, den Spiegel und/oder die Strahlbeugung erfolgt, bei der bspw. ein Elektronenstrahl mittels eines Magnetfelds gesteuert wird. Auf umfangreiche Steuerungsbewegungen der Strahlungsquelle kann gemäß dieser Weiterbildung der Erfindung verzichtet werden. Wie bereits eingangs dargelegt, kann die Erwärmung des Halbzeugs und/oder der zugeschnittenen Fahrzeugsitzkomponente an beliebiger Stelle erfolgen. So besteht bspw. die Möglichkeit, das Halbzeug vor der Platzierung in einer entsprechenden Schneidvorrichtung in einer separaten Heizvorrichtung zu erwärmen. Auch im Falle einer nachfolgenden Wärmebehandlung der ausgeschnitte- nen Fahrzeugsitzkomponente kann diese in einer separaten Heizvorrichtung durchgeführt werden. Beam diffraction makes it possible to use a radiation source, which is possibly already used for heating the semi-finished product, also for partial or complete heating of the cut vehicle seat component, the control and orientation of the radiation source taking place via the beam switch, the mirror and / or the beam diffraction in which, for example, an electron beam is controlled by means of a magnetic field. On extensive control movements of the radiation source can be omitted according to this embodiment of the invention. As already explained, the heating of the semifinished product and / or the cut vehicle seat component can take place at any desired location. For example, there is the possibility of heating the semifinished product in a separate heating device prior to placement in a corresponding cutting device. Even in the case of a subsequent heat treatment of the cut out vehicle seat component, this can be carried out in a separate heating device.
Nach einer vorteilhaften Weiterbildung der Erfindung ist jedoch vorgesehen, dass die Erwärmung des Halbzeuges und/oder der zugeschnittenen Fahrzeug- sitzkomponente in der Schneidvorrichtung erfolgt. Gemäß dieser Weiterbildung der Erfindung ist die Schneidvorrichtung, in der die Fahrzeugsitzkomponente aus dem Halbzeug getrennt wird, derart ausgebildet, dass sie eine Erwärmung des Halbzeugs und/oder der zugeschnittenen Fahrzeugsitzkomponente innerhalb der Schneidvorrichtung ermöglicht. Die Erwärmung kann dabei direkt über die Schneidvorrichtung erfolgen, welche entsprechend ausgestaltet ist oder die Schneidvorrichtung kann derart ausgestaltet sein, dass sie für geeignete Heizvorrichtungen den Zugang zum Halbzeug und/oder zur zugeschnittenen Fahrzeugsitzkomponente ermöglicht. Im Falle der vorteilhafterweise vorgese- henen Verwendung einer gerichteten Strahlung ist die Schneidvorrichtung gemäß dieser Weiterbildung der Erfindung bspw. derart ausgebildet, dass die Strahlung unmittelbar oder über vorteilhafterweise vorgesehene Umlenkvorrichtungen auf im Wesentlichen alle Bereiche des Halbzeugs und/oder der zugeschnittenen Fahrzeugsitzkomponente geleitet werden kann. According to an advantageous embodiment of the invention, however, it is provided that the heating of the semifinished product and / or the cut vehicle seat component takes place in the cutting device. According to this embodiment of the invention, the cutting device, in which the vehicle seat component is separated from the semifinished product, is designed such that it allows heating of the semifinished product and / or the cut vehicle seat component within the cutting device. The heating can be direct take place via the cutting device, which is designed accordingly or the cutting device can be configured such that it allows for suitable heating devices access to the semifinished product and / or the cut vehicle seat component. In the case of advantageously provided use of directional radiation, the cutting device according to this embodiment of the invention, for example, designed such that the radiation can be directed directly or advantageously provided deflection on substantially all areas of the semifinished product and / or the cut vehicle seat component.
Grundsätzlich lässt sich bereits durch eine geeignete Erwärmung eine gewünschte Materialeigenschaft der herzustellenden Fahrzeugsitzkomponenten erreichen. Nach einer besonders vorteilhaften Weiterbildung der Erfindung ist jedoch vorgesehen, dass die ausgeschnittene Fahrzeugsitzkomponente im An- schluss an den Zuschnitt aus dem Halbzeug gekühlt wird. Die Durchführung einer Kühlung, welche grundsätzlich in beliebiger Weise erfolgen kann, erlaubt es, die Härte und/oder Festigkeitswerte in besonders zuverlässiger Weise an die gewünschten Vorgaben anzupassen. Besonders vorteilhafter Weise ist dabei vorgesehen, dass die Kühlung, für die auch separate Kühleinrichtungen oder Kühlmittel verwendet werden können, durch Konvektion und/ oder Wärmeleitung in die Schneidvorrichtung, insbesondere in eine Spannvorrichtung der Schneidvorrichtung erfolgt. In principle, a suitable material property of the vehicle seat components to be produced can already be achieved by suitable heating. According to a particularly advantageous embodiment of the invention, however, it is provided that the cut-out vehicle seat component is cooled following the blank from the semifinished product. The implementation of cooling, which can be done in principle in any way, allows to adjust the hardness and / or strength values in a particularly reliable manner to the desired specifications. Particularly advantageously, it is provided that the cooling, for which separate cooling means or coolant can be used, by convection and / or heat conduction into the cutting device, in particular in a clamping device of the cutting device.
Gemäß dieser Weiterbildung der Erfindung kann die Schneidvorrichtung derart ausgebildet sein, dass sie zur kontrollierten Kühlung der ausgeschnittenen Fahrzeugsitzkomponente ausgebildet ist, wozu sie bspw. mit geeigneten Kühlkanälen versehen ist, die auch zum Anschluss von Kühlaggregaten ausgebildet sein können. Besonders vorteilhafter Weise ist jedoch vorgesehen, dass die Schneidvorrichtung, insbesondere eine Spannvorrichtung der Schneidvorrich- tung derart ausgebildet ist, dass die Kühlung durch Konvention und/oder Wärmeleitung in die Schneidvorrichtung erreicht wird, so dass auf separate Kühlvorrichtungen verzichtet werden kann, wodurch die Herstellungskosten in ergänzender Weise gesenkt werden können. According to this embodiment of the invention, the cutting device may be designed such that it is designed for controlled cooling of the cut-out vehicle seat component, for which it is, for example, provided with suitable cooling channels, which may also be designed for connection of cooling units. However, it is particularly advantageously provided that the cutting device, in particular a tensioning device, of the cutting device Device is designed such that the cooling is achieved by convention and / or heat conduction into the cutting device, so that can be dispensed with separate cooling devices, whereby the manufacturing cost can be reduced in a complementary manner.
Wesentlich für eine erfmdungsgemäße Fahrzeugsitzkomponente, insbesondere ein Bauteil für einen Sitzversteller eines Kraftfahrzeugsitzes, mit einem durch schneidtechnische Bearbeitung erstellten Randbereich und einem durch den Randbereich begrenzten Basisabschnitt ist, dass der Randbereich zumindest partiell eine größere Härte und/ oder Festigkeit als der Basisabschnitt aufweist. Der Randbereich der Fahrzeugsitzkomponente, insbesondere des Bauteils für einen Sitzversteller wird durch den Bereich definiert, der bei der Herstellung der Fahrzeugsitzkomponente aus einem Halbzeug im Bereich der schneidtechnischen Bearbeitung liegt. Dies sind insbesondere die Umfangsflächen der Fahrzeugkomponenten, wie bspw. hierbei hergestellte Verzahnungen, aber auch Öffnungen der Fahrzeugsitzkomponenten, welche bspw. dazu dienen, diese auf einer geeigneten Welle oder Achse anzuordnen. Essential for a vehicle seat component according to the invention, in particular a component for a seat adjuster of a motor vehicle seat, with an edge area created by cutting machining and a base section bounded by the edge area, is that the edge area has at least partial greater hardness and / or strength than the base section. The edge region of the vehicle seat component, in particular of the component for a seat adjuster, is defined by the region which lies in the production of the vehicle seat component from a semifinished product in the field of cutting processing. These are, in particular, the circumferential surfaces of the vehicle components, such as gears produced in this case, but also openings of the vehicle seat components, which, for example, serve to arrange them on a suitable shaft or axle.
Erfindungsgemäß weisen diese Bereiche zumindest partiell eine größere Härte und/oder Festigkeit als der Basisabschnitt auf, so dass die erfmdungsgemäße Fahrzeugsitzkomponente im Kontaktbereich die erforderliche Härte und/oder Festigkeit aufweist, andererseits im Bereich des Basisabschnitts eine Duktilität besitzt, welche im Crashfall den Abbau von Aufprallenergie durch Verformungsarbeit ermöglicht. Darüber hinaus weisen derartige Fahrzeugsitzkompo- nenten den Vorteil auf, dass für diese ein preiswertes und relativ dünnes Werkstück eingesetzt werden kann, nachdem die geforderten Härte- und Festigkeitseigenschaften in einem erforderlichen Bereich vorhanden sind. Besonders vorteilhafterweise werden die Fahrzeugsitzkomponenten dabei gemäß einem Verfahren entsprechend einem oder mehreren der Ansprüche 1 - 7 hergestellt. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung sind die Randbereiche der Fahrzeugsitzkomponenten dabei oberflächengehärtet, so dass der Basisabschnitt einen hohen Anteil an der Fahrzeugsitzkomponente besitzt und insgesamt bei ausreichender Härte und/ oder Festigkeit der Randbereiche ein hohes Maß an Energieabsorptionsfähigkeit durch Deformation durch die Fahrzeugsitzkomponente bereitgestellt wird. Besonders vorteilhafterweise ist der Randbereich dabei durch eine Wärmestrahlung, insbesondere gerichtete Strahlung gehärtet, wobei derart gehärtete Randbereiche die Ausbildung eines be- sonders großen Basisabschnitts ermöglichen. According to the invention, these areas have at least partially a greater hardness and / or strength than the base section, so that the vehicle seat component according to the invention has the required hardness and / or strength in the contact area, and on the other hand possesses ductility in the area of the base section, which in the event of a crash reduces the breakdown of impact energy made possible by deformation work. In addition, such vehicle seat components have the advantage that an inexpensive and relatively thin workpiece can be used for them after the required hardness and strength properties are present in a required range. Particularly advantageously, the vehicle seat components are produced according to a method according to one or more of claims 1-7. According to a particularly advantageous embodiment of the invention, the edge regions of the vehicle seat components are surface hardened, so that the base portion has a high proportion of the vehicle seat component and overall with sufficient hardness and / or strength of the edge regions a high degree of energy absorption capability is provided by deformation by the vehicle seat component. Particularly advantageously, the edge region is hardened by heat radiation, in particular directed radiation, wherein edge regions hardened in this way enable the formation of a particularly large base portion.
Ein Ausführungsbeispiel der Erfindung wird nachstehend in Bezug auf die Zeichnungen näher erläutert. In den Zeichnungen zeigen: Fig. 1 in einer perspektivischen Ansicht ein Bauteil eines Sitzverstellers und An embodiment of the invention will be explained below with reference to the drawings. In the drawings: FIG. 1 shows a perspective view of a component of a seat adjuster and FIG
Fig. 2 eine Spannungsverteilung in einer Verzahnung des Bauteils für den  Fig. 2 shows a voltage distribution in a toothing of the component for the
Sitzversteller und einem Ritzel bei einer unfallbedingten Last. Bei dem in Fig. 1 dargestellten Bauteil 1 eines hier nicht dargestellten Sitzverstellers handelt es sich um einen Gelenkarm eines Viergelenks zur höhenverstellbaren Lagerung eines hier ebenfalls nicht dargestellten Fahrzeugsitzes an einer nicht dargestellten Sitzschiene. Das Bauteil 1 weist zwei Ausnehmungen 2, 3 auf, welche im Bereich der Drehachsen des Gelenkarms ausgeschnitten sind. Eine weitere, bogenförmig geschnittene Ausnehmung 4 dient der Durchführung von Führungsmitteln.  Seat adjuster and a pinion in an accidental load. In the illustrated in Fig. 1 component 1 of a seat adjuster, not shown here is an articulated arm of a four-bar linkage for height-adjustable mounting of a vehicle seat also not shown here on a seat rail, not shown. The component 1 has two recesses 2, 3, which are cut out in the region of the axes of rotation of the articulated arm. Another, arcuately cut recess 4 serves to carry out guiding means.
Der Basisabschnitt 5 des Bauteils 1 weist eine besonders hohe Duktilität auf, damit das Bauteil 1 beim Auftreffen unfallbedingter Lastspitzen ein günstiges Energieaufnahmeverhalten aufweist. An einem Teil seines gleichfalls geschnittenen Außenumfangs ist das Bauteil 1 mit einer Verzahnung 6 ausgestattet, welche mit einem in Fig. 2 dargestellten Ritzel 7 eines Höhenverstellers in Eingriff befindlich ist. Abweichend von den Anforderungen an den Basisabschnitt 5 des Bauteils 1 ist gewünscht, dass die Verzahnung 6 eine ausreichende Härte und der Zahngrund 8 eine Festigkeitserhöhung gegenüber dem Basisabschnitt 5 aufweist. The base portion 5 of the component 1 has a particularly high ductility, so that the component 1 when hitting accidental load peaks a favorable Has energy absorption behavior. At a part of its likewise cut outer circumference, the component 1 is provided with a toothing 6, which is in engagement with a pinion shown in Fig. 7 7 a Höhenverstellers in engagement. Notwithstanding the requirements of the base portion 5 of the component 1 is desired that the toothing 6 has a sufficient hardness and the tooth base 8 has an increase in strength compared to the base portion 5.
Diese Eigenschaften sind dadurch erreicht, dass das Halbzeug, aus dem das Bauteil 1 durch schneidtechnische Bearbeitung herausgebildet ist, nur örtlich entlang der vorgesehenen Schnittführung, insbesondere im Bereich der Verzahnung 6 vor dem Feinschneiden erhitzt und zeitgleich oder vorzugsweise mit geringem zeitlichen Abstand geschnitten wird. Der Basisabschnitt 5 wird von dieser Wärmebehandlung somit im Wesentlichen nicht erfasst und behält seine ursprünglichen mechanischen Eigenschaften bei. These properties are achieved in that the semifinished product, from which the component 1 is formed by cutting machining, heated only locally along the intended cutting guide, in particular in the region of the toothing 6 before fine blanking and cut at the same time or preferably at a short time interval. The base portion 5 is thus substantially unaware of this heat treatment and retains its original mechanical properties.
